通过突变理论的尖点突变模型及分析,将地震信号转化为尖点突变的标准形式。在时间域、频域计算突跳势、突跳时间等突跳参数,分析突跳参数异常,较好的反映了煤层的不连续性;比较相干、突跳理论两种技术在反映煤层不连续性上的效果,分析了各种技术的优缺点。尝试将相干属性和突跳参数属性进行融合,得到新的属性切片,很好的反映了煤层断层和裂隙富集区的分布情况。研究表明,利用突变参数进行断层的检测是可行的,突变理论将为煤层不连续性检测提供一种新的方法。
Through the cusp catastrophe model and analysis of catastrophe theory, the seismic signal is transformed into the standard form of cusp mutation. In the time domain and frequency domain, sudden jump parameters such as sudden jump and sudden jump time are calculated to analyze the anomaly of sudden jump parameter and better reflect the discontinuity of coal seam. Compared with the coherent and sudden jump theory, The effect of sex, analysis of the advantages and disadvantages of various technologies. Attempts to merge the attributes of coherent and kurtosis parameters to obtain new attribute slices reflect the distribution of coal seam faults and enrichment zones well. The research shows that it is feasible to use the mutation parameter to detect the fault, and the catastrophe theory will provide a new method for the coal seam discontinuity detection.
